Olivia Tubb(5)

The most important relationship on her CV is with trainer Jonathan Portman. Across 32 rides together, Tubb has ridden 4 winners for the yard — that is 1 in every 8 races, or a 12% win rate, which is meaningfully better than her overall figures and suggests Portman keeps coming back to her for a reason. In racing, repeat bookings are the clearest sign that a trainer trusts what they see.

This season has been a little leaner. Four winners from 43 rides works out at roughly 1 in every 11 — down from closer to 1 in every 8 last year, when her win rate sat at 13%. That dip is worth watching, but it is not unusual for young jockeys to have an uneven patch as they take on tougher competition and the claims start to reduce. Seasons are long, and four winners is four winners.

Where Tubb does catch the eye is on normal ground conditions. In those circumstances she has won 3 races from just 14 — that is 21%, or roughly 1 in every 5, which is a genuinely sharp number. It hints at a jockey who is at her most effective when the track rides predictably, rather than when the ground is testing and unpredictable. On the right surface, with the right horse, she clearly knows what to do.

The one blot is her record with Brinton — six races together and no wins. It happens in racing; some partnerships simply never click. But with Portman in her corner, a decent overall tally of career winners, and still only three years in the saddle, the trajectory is positive. The next step will be turning those productive partnerships into big-day results.
